Most people associate arthritis with aging, but that's an oversimplification. The term covers more than 100 types of joint inflammation. The most common form—osteoarthritis—does increase with age, but rheumatoid arthritis (RA) can develop at any point in life, particularly among those between 30–60 years old.
Rheumatoid Arthritis Basics
RA is a chronic inflammatory autoimmune disorder in which the immune system mistakenly attacks healthy joint tissue. This leads to painful swelling, potential bone erosion, and joint deformity over time.
Symptoms often begin gradually, feeling worse in the morning and improving throughout the day. Early on, smaller joints—particularly those connecting fingers and toes—are typically affected first. As the condition progresses, symptoms spread and commonly impact matching joints on both sides of the body.
RA can also affect areas without joints, including:
- Eyes
- Skin
- Salivary glands
- Lungs, heart, or kidneys
- Nerve tissue
- Blood vessels and bone marrow
5 Common Signs of Rheumatoid Arthritis
Early diagnosis matters because RA is progressive. Here are five key warning signs:
1. Morning Stiffness
One of the earliest indicators of RA. Initially lasting only minutes, it can eventually persist for hours and interfere with getting out of bed.
2. Joint Pain or Stiffness
Pain, tenderness, or stiffness in smaller joints—present during movement or at rest, at any time of day—should not be ignored.
3. Joint Swelling
Inflammation may cause minor swelling lasting days to weeks, becoming more frequent over time. Rings fitting poorly or joints appearing larger than usual can be early clues.
4. Decreased Range of Motion
Untreated inflammation can compromise tendons and ligaments, causing deformity, instability, and difficulty bending or straightening joints. Tendon inflammation may also press on nearby nerves, producing burning, tingling, or numbness in the hands.
5. Fatigue
Because RA involves the immune system, it can disrupt sleep and produce flu-like symptoms—fatigue, low-grade fever, and reduced appetite—typically alongside joint symptoms.
With appropriate treatment, these symptoms can be managed and flare-ups minimized. Early evaluation at a pain specialist is strongly encouraged.
